MACHINE FOR CBIMPING MESHED WIRE.

To all whom it may concern:

Be it known that I, ARNO SI-IUMAN, of Gonnellsville, Fayette county, and State. of Pennsylvania, have invented an Improvement in Machines for Crimping, Meshed iVire, of which the following is a specification.

My invention has reference to machines for crimping meshed wire and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

The object of my invention is to form bent or crimped portions in open or meshed wire webs adapted for use as the metallic center in the manufacture of wire glass.

The general character of the crimped metal web and its use in the production of wire glass is shown in Letters Patent No. 727,004: and No. 727,005, dated May 5th, 1903, granted to Frank Shuman jointly with myself.

My present invention consists in a machine adapted to support and guide a meshed wire web and provided with dies for suitably crimping it at intervals in its surface.

More specifically, my invention embodies in a machine of the character above specified, two sets of dies, one set being to produce the sharp bends or crowns of the crimped portions and the other set being to bend the web intermediate of the sharp bends or crowns to increase the depth of the crimped portions and set the bends in the web. Y

My invention also comprehends details of construction which, together with the features above set forth, will be better under stood by reference to the drawings, in which:

Figure 1 is an elevation of a crimping machine embodying my invention; F ig; 2 is a plan view of same; Fig. 3 is a cross sectional elevation of the same; and Fig. 4 is a cross section showing a modification of the dies.

A is the main frame, B is the bed aid is provided with a longitudinal groove B in which is fitted the bed die C. This die C is preferably square in cross section and has each of its faces provided with a longitudinal V-shaped groove 0. These grooves may be of different depths to suit difi'erent webs having different thickness of wire. Thus for heavy wire web, the deepest groove 0 will be turned uppermost and inversely, 'for Specification of Letters Patent.

Application filed. February 25, 1907.

Patented Oct. 12, 1909. Serial No. 359,170.

the lightest wire web the smallest groove 0 will be directed upward. As shown in Fig. 3, the next to the largest groove is at the top. While I prefer to employ a bed die having more than one groove, 1 do not restrict myself thereto. It is also evident that the bed die may be formed and supported in other ways and its construction and manner of support are immaterial so long as it presents an upwardly directed face having alongitudinal groove with which the upper reciprocating die may cooperate.

D, D are upright guides, respectively at each end of the main frame for guiding the vertically reciprocating head E which carries at its lower part the longitudinal crimping die F having its lower edge made V- shaped and adapted to the grooves c in the bed die C. This die F is seated in a groove in the lower edge of the head E and is clamped in position by clamp bars 6 e drawn into clamping position by bolts G which pass through said bars and the head, as fully shown in Fig. 3.

H is a rotating shaft which is journaled in the main frame A below the bed and may be driven by cranks H or suitable power devices if so preferred. This shaft is provided with eccentrics I I near each end.

J J are links, extending from the eccentrics and pivoted at E to the journal pins at the ends of the head E. By rotating the shaft H, the head E is reciprocated vertically in its guides D The links J are preferably adjustable as to their length so as to insure the die F being properly adjusted to cooperate with the bed die C. This adjustment may be made by having the eccentric straps J and head E respectively screwed. on to the intermediate rod J by right and left hand screw joints, and held by lock nuts j. Any other manner of adjustment may be adopted in lieu of that shown.

Arranged to the rear of the bed die 0 and supported by the table are two forming die bars L L, said bars being clamped in place by clamps L at each end. These clamps L are bolted down to the bed B by bolts Z. By having the bars L L clamped in this manner they may be adjusted relatively to the bed die C and also with respect to each other if so desired, to suit the mesh of the web and shape of the crimps desired.

Cooperating with the forming die bars L L are two bending dies M M which are carl ried by brackets K attacliedto the head E, so that said bending diesM M are reciprocated vertically with the crimping die F. The bending dies M M are l1eld1to the"brackets K by bolts m and spacing blocks may be employed forproperly spacing the said dies to suit the positions of the crimps and die bars L L therefor. Any other manner of adjusting the dies M M to or from each other and to or from the crimping die F may be employed in lieu of that shown. The lower edges of these dies'l'ii M are preferably made vi-shaped to center themselves in the'V crimps in the web previously made by dies C F.

Arranged in front of the bed die C and supported in the bed is a bar N having a series of upright pins n. This bar is clamped by bolts N throughslots N in the brackets N andby which the bar is adjustable to or from the bed die G to suit webs having meshes of different sizes. The web S is placed over the pins n by hand and after each crimping operation by the dies, the web is advanced, being each time placed over the pins and pushed up against them to insure the proper extent of feeding of the web and theparallel alinement of the crimps.

The meshed wire Sis supported upon a spindle O loosely journaled on the main frame and from which the web is fed to the dies. W hen the web is crimped as indicated at T, it is then fed downward and wound upon a second spindle P at the rear of the machine.

In operating the machine, the meshed wire web S is placed between the dies 0 F by hand and adjusted against-the pins n; theshaft H is'then rotated one revolution, producing a crimp in the untwisted portion ofthe meshes of the web. This operation is repeated at equal distances apart, that is at each mesh or every other mesh as desired. As the web is fed forwardit will come between the die bars L L and dies M M and will have the crimps extended and defined as indicated at T T.

By using die bars L L having rectangular corners the bends in the setting of the crimps will be sharp or angular adjacent to the twisted portions of the web, but if the said bars are made curved on top as indicated in Fig. 4, then the crimps will connect by arch shaped portions of the web intervening.

hile I prefer the construction shown as being excellently adapted for the commercialuse of my invention, 1 do not restrict myself to the details as they may be modified without departing from the spirit of the invention.

llavingnow described my invention, what I claim as new and desire to secure by Letters Patent, is:
